GEORGE W. STOKES, OF PHILADELPHIA, PENNSYLVANIA.

JAGQUARD LOOM.

To all whom it may concern:

Be it known that I, GEORGE W. STOKES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Jacquard Looms, of which the following is a specification.

My invention relates to improvements in Jacquard looms, the object of the invention being to provide an improved mounting for the cards of Jacquard looms, whereby without stopping the loom, certain of said cards may be disconnected from other of said cards and elevated to a position out of the way of the remaining cards, yet in position to be readily returned and used when desired.

Heretofore looms which are particularly designed for weaving carpets and rugs having borders, have been equipped with cards containing a section of border and a section of the body of the carpet or rug. After the border has been woven and a portion of the body, it has been necessaryto turn the cards backwardly after each section of the carpet has been woven.

It is the purpose of my invention to pro-- vide an improved elevator construction which enables the border cards to be elevated and the ends of the body cards connected, so that an endless series of body cards remain on the loom to permit the body of the rug or carpet to be woven in any length desired, and when the desired length is had, permit the border cards to be again connected with the body cards and the border of the carpet or rug integrally woven at the end of the-length. To facilitate this movement and the ready connection and dis connection of the cards, I preferably employ quick detachable fastening devices between the cards which form the subject matter of my application for patent filed March 1, 1912 and given Serial No. 680,821.

With these and other objects in View, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims. 7

In the accompanying drawings: Figure 1 is a diagrammatic view illustrating my improvements in side elevation showing the elevator in its lowest position. I Fig. 2 is asimilar view showing the elevator in its Specification of Letters Patent.

highest position. Fig. 8 is a plan view illustratlng my improved arrangement of cards which enable the quick connection and disconnection of the same. Fig. 4 is a view in vertical section on the line 14: of Fig. 5. Fig. 5 is a view in end elevation on an enlarged scale. Fig. 6 is a fragmentary view in section on an enlarged scale on the line 66 of Fig. 5. Fig. 7 is a perspective view of one of the end rod supporting tracks 22 of the elevator, and Fig. 8- is a similar view of one of the intermediate rod supporting tracks 21 of the elevator.

While my invention might be adapted for use on various forms of loom, it is particularly adapted for use in connection with a carpet loom and especially with such a loom designed for weaving rugs and bordered carpets.

I have therefore, illustrated my invention in connection with no particular type of loom, but show diagrammatically in Figs. 1 and 2, a frame 1 to indicate a loom structure having brackets 3 thereon in which the rotary cylinder 4: is mounted to turn, and over this box the cards 5 are adapted to move.

Secured to the ceiling 6 or any other sup port, and located in a convenient position relative to the loom, preferably above the lay, is my improved rectangular frame which comprises a plurality of vertical hangers 7 secured at their upper ends to the ceiling or other support and connected at their lower ends by transversely positioned horizontal bars 8. I employ as many of these hangers and bars as desired in accordance with the number of sections of cards in use on the loom.

The bars 8 are spaced apart a distance sufliciently greater than the length of the cards to allow the cards to freely swing downwardly between the said bars and the rods connecting the series of cards are supported normally upon the bars 8. I have indicated in Fig. 3, a plan view of my improved arrangement of cards in which I employ snap buttons 9 to connecttapes 10 on the ends of the series of cards 11, and the wires which connect the cards of the sev eral sections, I have given reference numeral 12.

It is to be understood that the border cards at both ends are connected to the body cards by improved quick detachable means,

as for example, by the snap buttons, and the said cards move in order over the cylinder 4, thence downwardly to a position between the bars 8. This movement is guided by inclined bars 13 which may be fixed at their upper ends in any suitable manner and at their lower ends connected to the end bars 8, 'so that the wires 12 at their ends slide upon the inclined bars 13, and find lodgment and rest upon the bars 8.

As the wires collect 011 the bars 8, they are moved forwardly by the accumulation of wires back of the same and the cards from the forward end of the sections pass over an idle roller 14, and thence back to the cylinder 4. The end bars 8 are also connected to the ceiling or support 6 by means of parallel vertical guide bars 15, the latter having guide recesses 16 in their inner faces as clearly shown in Fig. 6.

I-bars 17 are mounted to slide between the guide bars 15, and these I-bars 17 are preferably made up of three separate and distinct strips which are secured by transverse rivets 18. The smaller strip or intermediate member of the I-bar, slides bet-ween the bars 15, while the inner member of the I-bar slides in the grooves 16 and is substantially flush with the inner face of guide bars 15.

The I-bars 17 are connected at their lower ends by strips 19 with vertical wire supports 20. One of these wire supports is shown most clearly in Fig. 8. At their upper ends, they are elongated transversely forming tracks 21 which curve downwardly at their ends to form sharp edges joining the edges of bars 8.

The vertical wire supports 20 are preferably formed of a single piece of sheet metal extended transversely bet-ween their ends and bent to form the tracks 21, the two ends of the wire supports positioned at opposite sides of the bars 8, and preferably of a length to maintain the connecting strips 19 out of the Way of the cards hanging from the wires as clearly shown in Fig. 4. While I have illustrated three of these intermediate wire supports, it is to be understood that as many may be provided as are necessary to accommodate bet-ween the end bars 8 the desired number of sections of cards.

The I-bars 17, in line with tracks 21, are provided with tracks 22. These tracks 22 have integral downwardly projecting lugs 2 1 and 25, the former adapted to be secured to the I-bars', and the latter adapted to engage the inner face of the end bars 8, so as to support the tracks 22 directly above the end bars 8. In other words, the tracks 21 and 22 are in alinement and positioned directly above the bars 8. In fact, the tracks 21 and 22 when in position on the bars 8, constitute a part of the surface upon which the wires 12 ride and are supported.

The I-bars 17 are connected by a transverse bar 23 which is positioned above the tracks 21 and 22 sufficiently to allow the wires to move freely thereunder.

The I-bai's 17, strips 19, tracks 21 and 22, and bar 23 constitute an elevator which moves vertically and is guided between the bars 15. This elevator is balanced by means of a weight 26, the latter being connected by ropes 27 with bar 28, said ropes passed over pulleys 28 as indicated in Fig. 1. In other words, the weight is designed to balance the elevator, so that it will require but little power to move the same.

To operate the elevator, I provide levers 29 which are secured between their ends upon a shaft 30, and the latter mounted in brackets 31 depending from the ceiling. These levers 29, at one end, are connected by links 32 with the lower ends of the I-bars 17 and at least one of these levers, at its other end, is provided with a depending rope 33 which terminates in position to be readily grasped by the operator.

Any suitable means, may of course be provided to positively hold the elevator in its highest position if desired, but the elevator may be nicely balanced by means of the weight 26, so that it will, under normal conditions, remain in any position to which it is moved.

The operation is as follows: In weaving a rug, the intermediate lengths of the rug are formed with border sections at the ends of the lengths, and the body portion between the bordered ends. The cards on the loom, when the weaving operation begins, presentfirst for operation, the cards forming the border and then a short length of the body. These cards for the body are then used over again as many times as it is desired according to the length of the rug, and then the border cards are again brought into operation. Vith my improvements, as soon as the border is formed, the cards which form the same will be positioned over the elevator with the wires 12 of such cards supported upon the tracks 21 and 22. The operator then disconnects the border cards from the body cards and moves the elevator -to liftthe border cards out of the way. He then connect-s the ends of the body cards and permits the loom to operate repeating the body cards as many times as desired, because they are connected together and form an endless chain of cards. When the desired length of body is woven, the end cards of the body cards are disconnected and connected to the end cards of the border cards, so that the border may be woven in again at the end of the length.

By means of a structure of this kind, it will be noted that the border cards may be taken out at any time desired, that the body .OiLI'ClS IIRLy be used over and over again withuse, and by providing the cards with quick detachable means such as explained, this operation may be readily carried out.

Various slight changes might be made in the general form and arrangement of parts described without departing from my in vention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the Spirit and scope of the appended claims.
